  • Please bring a laptop and power cord to class – each class will be centered around hands-on exercises.
  • Before class, please install both R and the RStudio IDE, and ensure that your computer can connect to the internet. We will use the following R packages in class, so you should install them ahead of time:
  • tidyr, devtools, dplyr, ggplot2, scales, rmarkdown, knitr, DT, shiny, DBI, and RSQLite as well as the reportsWS package which must be installed with the command:


From advanced visualization, collaboration, and reproducibility to data manipulation, R Day at Strata covers a raft of current topics that analysts and R users need to pay attention to. The R Day tutorials come from leading luminaries and R committers, the folks keeping the R ecosystem apace of the challenges facing analysts and others who work with data.


R Quickstart: Wrangle, transform, and visualize data
Instructor: Garrett Grolemund
90 minutes

This 90 minute quickstart will teach you the most used–and most powerful–parts of the R language. You will learn the best ways to perform the core tasks of data science:

  • How to wrangle your data (with the tidyr package)
  • How to transform your data (with the dplyr package)
  • How to visualize your data (with the ggplot2 package)
  • These fast and intuitive packages will provide a solid foundation for everything else you do in R.

Work with Big Data in R
Instructor: Nathan Stephens
90 minutes

R is the go to language for data exploration and development, but what role can R play in production with big data? In this class, RStudio’s solution engineer demonstrates a pragmatic approach for pairing R with big data. You will learn to use R’s familiar dplyr syntax to query big data stored on a server based data store, like Amazon Redshift or Google BigQuery. We will also discuss how to generalize the process to other big data stores, and how to best leverage R within a big data pipeline.

Reproducible Reports with Big Data
Instructor: Yihui Xie
90 minutes

This tutorial will teach you a time-saving workflow that has become the new standard for reproducible research. The R Markdown package makes it easy to document both your code and your results in the same file. With an R Markdown file and the click of a button, you can
re-execute your analysis with the most up-to-date code and data to create new results, and/or
generate a polished report in a variety of formats (html, pdf, Word, etc.) to share your results
This class will demonstrate some best practices that further increase the efficiency of reproducible research with R Markdown.

Interactive Shiny Applications built on Big Data
Instructor: Garrett Grolemund
90 minutes

R’s Shiny package lets you move beyond static reports to easily build interactive applications powered by R. Run your Shiny apps locally, or share them over a server with clients, customers, and colleagues. Your visitors will be in the driver seat. They can explore data, monitor dashboards, run R analyses, or do anything else you prepare for them all without knowing any R code. If a picture is worth 1000 words, a Shiny app is worth a million. In this tutorial, you will learn the basics of creating Shiny apps, as well as the best practices for using big data with your apps.

I am trying to install ggplot2 but I am getting a message error of package ggplot2 is not available (for R version 3.1.2)
Is there a different version of R that I should be working with?

Hi Garrett,
Thank you.

The “load” commands worked fine (once I noticed and fixed the fact that copying and pasting the commands from this website into RStudio on PC put the wrong kind of double quotes around the url).

It took me a few trials to get to the point where I noticed the problem with the double quotes, and in the process of poking around I had tried utils::setInternet2()
I do not know whether this step was necessary or not for enabling the load commands to work, so I am mentioning it in case other people with corporate laptops are having trouble.

See you at the tutorial.

Hi everyone,

Some students have reported curl related trouble installing the reportsWS package from github, and others may have had trouble but not reported it.

These error messages usually suggest that you are downloading from behind a firewall or proxy server that is not configured to allow downloads from github (a common scenario on corporate networks). Your IT team may be able to help you fix the problem, if you wish.


We will have a back up server with the package installed that you can use at the conference if necessary.

We will only use the reportsWS package for the data sets that it contains. If you would like to have those data sets on your local computer, you can download them and load them into your R session one at a time with the code below. Each line will create a data frame with the name of the .rdata file. Note that this method will only work on a computer/network that allows downloads from Also note, as mentioned above, that this will not not be necessary to participate in the class.


WHY YOU SHOULD WORRY is a widely used resource in the R community. Many R packages are developed and disseminated through If you would like to become a flexible R user, it will be important to acquire the ability to install packages from onto the computer that you use.

Sorry, I should have mentioned: I am on a Windows 7 corporate laptop. I did download the latest version of R and of RStudio.

I tried to download the required packages.
I was not able to install reportsWS. (Y=The other recommended packages installed without a problem).

Here is what I tried.

Rajesh, It looks like you are right about the registration options. Or perhaps the one day tickets have sold out. As speakers, we aren’t involved with the registration decisions.

Just a couple quick notes:
For some reason my browser kept loading a cached version on this site so I never saw the agenda when posted.

Last year, there was an option for one-day registration for just R-day. That does not seem to be available this year – or did I miss it?

Just to be clear. The final agenda is now displayed on this webpage. I look forward to seeing everyone at R Day!

Apologies if I missed it but is there an agenda yet for this?
